List your analog hardware here if Keyrite files sound bad to you

[jahern]

I have plugged my computer into bmb karaoke mixer, koss receiver amplifier, cheap computer speakers. I have also used my mdrv6 sony headphones as the only listening source. (plugged right into the computer)

I have used three different sound cards, including sound blaster live, on two different computers. I always hear a quivering sound. (I use keyrite all the time for myself.) I feel that my mixer sounds better when I change keys. However there are some disadvantages there.
